iPad app for using Apple Pencil in Scrapbox

• I wish I could replace Scrapbox with something like GoodNotes.

• It seems like using PencilKit or SwiftyDraw would make the drawing part easier.

• Current issues with Scrapbox’s standard drawing feature:

  • Simply put, it lacks functionality.
  • You can’t move or resize something you’ve already drawn.
  • There are only a few colors available.
  • It feels a bit clunky.

• We can enhance these features by relying on PencilKit.

  • Like this:
  • 

• With improved functionality, it seems possible to use Scrapbox as a replacement for GoodNotes.

  • It could address the inconvenience of GoodNotes.
    • When the pencil runs out of battery, it’s difficult to type in GoodNotes (because it lacks typing functionality).
    • Even in cases where typing is better than writing, I feel more inclined to use handwriting in GoodNotes.
  • It would be great to have an implementation that allows for smooth switching between typing and handwriting.

• It is already possible to write with PencilKit and upload it.

• The problem lies in difficult re-editing.

  • It might be a good idea to record the latest version on the page using JSON or base64 and also make it viewable as an image.
  • It seems surprisingly feasible to implement.
  • Maybe using scrapbox.io/files.
    • Scrapbox File Upload
  • Since I’m not sure about the specifications of the file API, it might be better to record the JSON in a code block.

• I would like it if the highlighted parts with a highlighter pen could be read by OCR and recorded as links or hashtags.

Implementation

• WKWebView
  • Since Scrapbox is an SPA, the load event is not triggered.

    • This solves the problem.

Ideas not to be implemented §

• I lost motivation, so I’ll put it on hold for now.
• I might work on it if I feel like it.
• I’ll pay my respects on Twitter.
